Abstract: PURPOSE:To execute easily and exactly a test, utilizing sufficienty an advantage in respect of reproducibility, durability and maintenance of a DC dynamo meter, providing additionaly a circuit for making a characteristic of the DC dynamo meter approximate to a characteristic of an engine. CONSTITUTION:When a car speed is set by a setting device 13, a car speed command is obtained in an AVR15 is accordance with a deviation of its set value from an output (detected value) of a rotation/car speed transducer 12. This command becomes within a range of the maximum rotational frequency corresponding to an engine and an idling value. The car speed command is compared with an output of an F/V transducer 14 showing the rotational frequency of a dynamo meter 5, a control signal of a value corresponding to its deviation is outputted from an ASR16, and it is supplied to the DC dynamo meter 5 through an ACR17. That is to say, the rotation of an eddy current dynamo meter 4 is controlled at the side of the DC dynamo meter 5. In this case, a characteristic of the DC dynamo meter 5 is made approximate to a characteristic of an engine.

Title: Manufacture of ceramics superconductive wire material
Inventor: SHISHIDO HIROSHI
IPC: B21B1/22
Filed: 1988-04-14
Abstract: PURPOSE:To obtain a material having the quality of superconduction, particularly higher critical electric current density by applying powders made up of the same material as a filling material to the surface of an outer cover material and annealing it after cold rolling the outer cover material filled with ceramics superconductive powder to form it in a line- or belt-shape. CONSTITUTION:After weighing powders of yttrium oxide, barium carbonate and copper oxide to form a desired compound, mixing these powders uniformly and molding them, the powders are calcinated at 950degrees centigrade and broken into pieces again. Then the powders are filled into an outer cover material made up of silver or an alloy of silver and this is processed to a fixed size by wire drawing cold rolling. The next process is to apply mixed liquid made by mixing and kneading the calcinated powders with organic binder whose viscosity is comparatively higher to the outer side of the processed outer cover material. Next, after the wire material is annealed at 900-100degrees centigrade, the temperature is slowly lowered to 400-600degrees centigrade and kept at 400-600degrees centigrade for several hours to adjust the density of oxygen and after that slowly lowered. This process can provide a material having the quality of superconduction, particularly higher critical electric current density.

Title: Ink cartridge
Inventor: TERASAWA HIROHARU
IPC: B41J2/20
Filed: 1983-05-25
Abstract: PURPOSE:To securely prevent contamination from being generated due to leakage of an ink, by a method wherein an ink plug fitted to an ink cartridge is provided with a capillary passage, while an ink-absorbing body communicated to the capillary passage is provided in the interior of the cartridge. CONSTITUTION:As a hollow needle 7 is drawn out from a rubber plug 3, slight leakage 8 and 9 of the ink from the cavity and the interior of the needle 7 is generated, and the leaked ink adheres to the surface of the plug 3. In addition, when the needle 7 is left as drawn out, the ink remaining in the interior of the needle 7 leaks out to a tip part of the needle 7 under the effect of a temperature change or the like, and adheres to the surface of the plug 3 in a manner similar to the above when the cartridge is subsequently fitted. When the ink adhering to the surface of the plug 3 makes contact with the capillary passage 6, it becomes absorbed into the interior of the passage 6, and is absorbed into the ink-absorbing body 5 provided in contact with the passage 6.

Filed: 1988-04-12
Abstract: PURPOSE:To facilitate to adjust each optical element, and to improve focus detecting sensitivity by making the incident angle of an approximately parallel light flux against a prism smaller than an outgoing angle from the prism. CONSTITUTION:An optical lens 21 upon which the light flux from an object to be detected is made incident, the prism 22 upon which the light flux from the optical lens 21 is made incident and a light receiving element 23 to which the light flux from the prism 22 is led and which detects the focusing state of the optical lens 21 for the object to be detected are provided. Then, on the assumption that the light flux going from the optical lens 21 toward the prism 22 is approximately parallel light flux when the optical lens 21 is in a focused state for the object to be detected, the prism 22 is arranged so that the incident angle (u) of the approximately parallel light flux against the prism 22 comes to be smaller than the outgoing angle (y) from the prism 22. Namely, when the prism 22 is arranged so that the incident angle (u) < the outgoing angle (y), deltau<deltay. Namely, dislocation quantity comes larger compared with the case of no prism. Thus, each optical element can be easily adjusted, and the focus detecting sensitivity can be improved.

Title: Speed control device of inverter for elevator
Inventor: IIDA MITSUHIKO
IPC: H02P27/06
Filed: 1994-04-28
Abstract: PURPOSE:To reduce the traveling time by limiting the acceleration command to the lower value as the output current becomes the higher to suppress the increase of the output current, and continuing the acceleration while the output current is kept in the range lower than the overcurrent stop level. CONSTITUTION:In the range where the output current of an inverter 4 is increased, and exceeds the first overcurrent limit level of an acceleration limit operating part 16, the degree of increase of the acceleration command, i.e., the acceleration is limited, and the acceleration is continued while the stop by the overcurrent is avoided. The limit of the acceleration command when the overcurrent is limited by the acceleration limit operating part 16 reduces thc value of the coefficient Klim to be multiplied to the acceleration of the acceleration command. When the output current is increased even if the acceleration is reduced, the acceleration is further reduced, and the acceleration is finally limited to zero. The present speed V1 is continued for the period T1 as specified in the formula since the deceleration starting point is reached, and deceleration and stopping is made at the same deceleration as that of the speed pattern V after the period of T1.
